Abstract
Conversion of 5-hydroxymethylfurfural (HMF) to 2,5-dimethylfuran (DMF) by electrocatalysis is significant but challenging. A Cu–POx catalyst (CuP-CF-350-H), synthesized by simple electrodeposition, shows high efficiency for C–O cleavage by suppressing the side reaction of aldehyde hydrogenation, and achieves 63.1% DMF selectivity at 92.0% HMF conversion. The synergistic presence of electron-deficient Cu sites and POx species provides a large number of active sites for proton stabilization and HMF adsorption, as well as the acidic sites for C–O cleavage. In addition, the oxygen-deficient POx species in the catalyst promotes the spillover of Hads (H*) from Cu sites to POx, reduces the surface H* coverage, and provides a sufficient number of protons for hydrodeoxygenation.
期刊介绍:
Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
